Kim Kardashian left the studio on Sunday in Los Angeles, and when she climbed into her Mercedes SUV, she needed help from an assistant at the studio to make sure she didn't flash the dozens of photographers camped outside.

Kim and hubby Kanye West returned from their romantic Mexican vacation on Thursday night, and it looks like she'll be here for a while. Kim was only supposed to spend about a month shooting with sisters Khloe and Kourtney for their spin-off reality show in the Hamptons, and she hasn't been back to New York for several weeks now. Still, looks like she was busy shooting the confessionals for the show ... she may be famous for nothing, but she's certainly one hard worker!
